| 748 misfiring.....
After spending some time on an m900 and 900ss I decided to get a 748 - so I now have a misfiring 748 which is driving me nuts.
The misfire only appears to happen after I've used around 90 miles worth of fuel then the misfire kicks in - won't rev and sounds very sick. Changed the plugs, drained the tank and replaced the filter - all fuel lines look ok / no kinks, breather is clear. It starts first prod from cold and will restart even after the misfire kicks in. Refilling the tank appears to solve the problem - until the fuel level gets down to around the same point....... any ideas?
Thanks G. |
